The Active Ingredient Is: 5-HTP (5-hydroxytryptophan)

5-HTP is a naturally occurring amino acid derivative that acts as a direct serotonin precursor in the body.

It is sourced from Griffonia simplicifolia seeds and supplied in a vegan capsule, offering a clean-label, allergen-conscious ingredient.

What Does 5-HTP Do?

5-HTP plays a role in normal serotonin production, which is linked to mood, sleep and appetite regulation.

This mechanism involves crossing the blood-brain barrier to support central serotonin levels, aligning with guidance on serotonin's role in everyday physiological regulation.

Scientific evidence suggests that 5-HTP is a serotonin precursor that can influence mood, sleep and appetite through its action in the brain.
